TLX-8 double sided PCB bulit on 10mil substrates with plating ENIG Finish for Microwave Applications

2-Layer PCB with TLX-8, 0.3mm Thickness, and ENIG Finish for Microwave Applications
(All PCBs are custom-manufactured. Reference images and parameters may vary based on your design requirements.)


1. Overview of the 2-Layer PCB
This 2-layer PCB uses Taconic TLX-8 laminates, a PTFE fiberglass material renowned for its outstanding thermal resistance, low dissipation factor, and stable dielectric constant. With a 10mil TLX-8 core, surrounded by 1oz copper layers on both sides, this PCB ensures signal integrity, durability, and reliability in extreme environments.
The ENIG surface finish provides excellent solderability and long-term corrosion resistance. While this PCB does not include solder masks or silkscreens, its compact size (20mm x 21.35mm) and precise manufacturing make it a top choice for high-performance microwave applications.

4. Features of Taconic TLX-8
The TLX-8 laminates are designed for microwave applications requiring low loss and high reliability. Below are its standout features:

• Dielectric Constant (Dk): 2.55 ± 0.04 at 10 GHz, ensuring stable signal propagation.
• Dissipation Factor (Df): 0.0018 at 10 GHz, minimizing signal loss.
• Tg: >535°C (2% weight loss) and >553°C (5% weight loss), ensuring reliable performance in high-heat environments.
• X-axis: 21 ppm/°C.
• Y-axis: 23 ppm/°C.
• Z-axis: 215 ppm/°C, ensuring dimensionally stable plated-through holes.
• Moisture Absorption: 0.02%, ensuring reliability in humid environments.
• Flammability Rating: UL 94 V-0, meeting stringent safety standards.
